1 Application fildiNovelilber 23;. 1 923. r

This invention relates to coupling devices and has special reference to devices for connecting an automatic M. C. B. coupler head with a hook-type coupler, the object of the invention being to provide a connection which will be permanently connected with the M. C.- B. coupler head so that loss and theft will be guarded against, to utilize parts which are now standard equipment in the hook coupler and thereby keep down the cost of installation, and to provide a connection which will readily ac.- commodate itself to unequal loading of the cars and will not interfere in any way with the usual operation of the automatic M. G B. coupler. The invention is illustrated in the annexed drawings and will be hereinafter fully set forth.

In the drawings, Figure l is a plan view of the improved device; 1

Figure 2 is a side view of the same under pulling strain;

Figures 3 and at the cars in buffing trating variations in loading of the cars;

Figure 5 is a detail.

The M. C. B. coupler head 1 is, in the present instance provided on the outerside of the guard arm withan eye 2 preferably slightly elongated and diverging forwardly from the longitudinal axis of the head. On the opposite side of the head and alined transversely with the center of the eye is a headed stud 3, the head of which is flattened on its opposite side edges whereby it is given a substantially elliptical form with its major axis inclined downwardly and rearwardly, as shown in Fig. 5. The device includes a triangular link etwhioh is engaged over the hook coupler 5 and which is engaged and carried by the clevises 6 which are part of the usual equipment of the hooktype coupler. Clevises 7 and pins 8 connecting them to the clevises 6 are'also employed and these parts are also usual equip ment on the hook-type coupler. In assem- I bling the parts, one clevis 7 is engaged over the stud 3 and the other clevis 7 is engaged through the eye 2; the ends of tive clevises 6 are then fitted'in the open ends of the clevises 7, as shown in Fig. 2, and the pins 8 insertedthrough the ends of the clevises. Small locking pins 9 are inare side views showing pos1t1on and also illusposition due to unequal the respec-' Serial no; 676,573.

permanently attached to the coupler head,

at least to sucha degree that they can be removed only with the use of efiicient tools and after laborious effort.

lVhen two automatic couplers are brought together so that the use of the transition device herein described is unnecessary, the device is suspended below the coupler head from the eye 2 and stud 3 so that it will be out of the way and will not interfere at all with the operation of the couplerhen a car with the hook-type of coupling is coupled to a car fitted matic coupler carrying this improved device and the cars are separated under. pulling strain, the clevises and the triangular link will be substantially in alinement, but when the pulling strain reduces and the cars come together in bufling position, the device folds downward and swings more or less under the coupler head accordingly as one or the other car is carrying the heavier load, as will be understood on reference to Figures 3 and 4:.

Instead of of the head, eyes 2 may be provided at both sides of the head. I

By referring to understood that if inclined position so coincide with or lie parallel to the major axis of the stud 3, it may be easily shifted into engagement with the stud behind the head thereof and the head will prevent its disengagement or release under all ordinary conditions as, in order to be released, the link must be rocked transversely while its length extends in the same direction as the length of the stud. The obliquely disposed eye 2 and the shank of the stud permit a limited play of the links to accommodate the movement of the cars each other as the pulling strain increases or decreases and will accommodate the relative angular movement of the cars in rounding curves without permitting detachment of the links. It will also be noted that the links are mounted on the head without requiring any additional openings to be formed through the head to weaken the same or the employment of any extraneous retaining-devices.

In testimony whereof, we have specification.
